Summary:PURPOSE:To obtain the titled resin with good delustered appearance, by dissolving diallyl phthalate prepolymer in vinyl chloride monomer or its mixture with another monomer copolymerizable with it followed by graft copolymerization. CONSTITUTION:The objective resin can be obtained by dissolving (A) a diallyl phthalate prepolymer (pref. with an average molecular weight 4,000-30,000) in (B) vinyl chloride monomer or its mixture with another monomer copolymerizable with it (e.g., ethylene) (preferably with a weight ratio (A)/(B) of 0.5-20/ 99.5-80 followed by graft copolymerization, pref. in the presence of radical polymerization initiator (e.g., azobisisobutylonitrile) through aqueous suspension process.
